AUGUST KLIIMPP, OF-MUNICH, GERMANY, ASSIGNOR TO THE DAYTON AUTOLEGTRIC CO., OF DAYTON, OHIO, A CORPORATION OF NEW JERSEY.

SPECIFICATION forming part of Letters Patent No. 730,132, dated June 2, 1903.

Application filed May 23, 1902. Serial No. 108,684. (No model.)

To all whom t 77th/y concern.-

Be it known that I, AUGUST KLUMPP, a citizen of the German Empire, residing at Munich, in the Kingdom of Bavaria, Germany, have invented certain new and useful Improvements in Automatic Display Mechanism, of which thefollowing is a full, clear, and exact description.

My inventionrelates to improvements in mechanism for automatic display mechanism .l More particularly it relates to the carrying out and rendering automatic.V my former iu- Vention, as disclosed in Letters Patent No. 633,650, issued to me September 26, 1899.

The object of my invention is the better understood by reference to my said l'atent No. (533,650. Therein I have shown means for successively presenting a series of pictures or views by means of a plurality of endless chains or belts, each carrying a speciiic section of each picture or view and so arranged and operated that the several sections are successively'brought into a common plane, so as to present a substantially unbroken surface. This involves requirements which I have met in my present invention. The sections must be periodically moved. Themovement should be automatic. They must be stopped, and should be stopped automatically, and during the period of rest the mechanism having intermittent movement must be so arrested and held as to insure the presentation of the section in plane.v

Since the motive power, whether electricity or other power, should be preferably constant in action, it is essential that mechanism giving an intermittent movement be interposed.- My present invention provides such means, and, further, provides'means for operating all of the sections by a single motor or source of power and means for the proper adjustment and regulation ofthe Vseveral parts.

Referring to the drawings herewith, coilsisting of three sheets,"in which like characters of reference indicate corresponding parts, Figure 1 is an end elevation. Fig. 2 is a plan view of the operating mechanism and mechanism giving intermittent movement.

- Figs. 3 and 3lL are detail views in elevation,

Fig. 3 showing the position of the mechanism producing the intermittent movement at one 'sprockets 3.

point-in the period when the intermittently moving parts are at rest, and Fig. 3a showing the locking mechanism atl the same point during the period -when the intermittently moving parts are at rest. Fig. 4 is a horizontal section on the line .fr a'. of Fig. 1, the` driving-chains being omitted.

Referring to Figs. 1 and 4, 1 represents the plates to which the sections or segments of the pictures or views are pasted or otherwise secured. 2 represents the driven chains, carrying the plates 1, and 3 and 4 are the sprockets over which the chains 2 are carried. These elements will be recognized as the construction and mechanism disclosed and claimed in my said former patent, which are operated by my present invention, the principal parts, construction, and operation of which I will now describe. l

` lteferringl especially to Fig. 2, 5 is an electric motor having a continuous motion in rotation. A shaft 6, carrying a worm 7, actuates a gear 8. The-worm 7 and gear 8 are preferably set in an oil-containing box 9 to secure perfect lubrication. A pin-ion 10,

mounted in rotation with the gear 8, meshesI with a gear 11,`which through bevel-gears `12 and 13 gives motion to the shaft 14. Upon the shaft 14 are mounted a segmental spurgear 15 and a recessed disk 16, These several parts have a constant movement in rotation. A Vshaft 17, mounted in bearings, carries sprockets 18 at either end,over which drivingchains 19 pass. These chains engage sprockets 20, (see Figs. 1 and 4,) which' are mounted rigidly upon the pivots which carry the Thusthe motion of the shaft 17 is communicatedto the sprockets 3, the

chains 2, and the plates 1. This motionis an intermittent movement, produced in the following manner: The 'segmental gear 15 on the shaft 14 acts upon a spur-gear 21 upon the shaftl?.v The segmental' gear 15 is an arc of suflicient length to impart a half-revolution to the spur-gear 2l for each revolution of the shaft 14, so that if the. segment 15 be one-sixth, say, of the circle constituting its path it is evident that an intermittent movement will be communicated to the plates 1, wherein they will be at rest five-sixths of the time. As it is essential that the end of each intermittent movement be at a definite point in order to secure absolute alinement in plane of the plates 1l when presented to View, I mount a recessed disk 16 upon the shaft 14 and a double cam 22 upon the shaft 17. The cam 22 has concave ends, which have a radius equal to the radius of the disk 16 and which are so situated as to take over the periphery of the disk 16, as is clearly shown in Fig. 3. The disk 16 is recessed, as clearly shown at 23. This recess is positioned with reference to the gear-segment 15 so that when the gearsegment 15 engages the gear 21 the cam 22 may turn out of engagement with the disk 16, allow the shaft 17 to make a half-turn, as shown in Fig. 1, and the other concave end of the cam to come into engagement over the disk at the end of the movement. Such movement will carry one set of plates 1 out and another set of plates in to position to display7 a picture or view. tuate the sprockets 20, as above stated; but, as is evident, some means must be afforded to hold such a chain in working contact with a series of sprockets occupying a vertical position. This I accomplish in the following manner: I provide vertical plates 24, secured to the frame of the machine and so placed as to constitute a back bearing for the vertical portions of the chains 19, engaging the sprockets 20. The slack of the chains is taken up by adjustable rollers 25, which are pivoted in yoke-bearings 26. The rollers 25 have flanges taking over the sides of the chains. The yokes 26 are adjustable by screw-threaded bolts 27, pivoted to the frame of the machine, and are held against vibration by brace-bars 28. By adjustment of the nut shown in broken lines in Fig. 1 situated within the yoke 26 and setting the nut external to the yoke the slack of the chain 19 is taken up, so as to prevent binding or jumping which would otherwise occur between the sprockets 2O and the plate 24. It is also essential that the driven chains 2 should be adjustable. The sprockets 3 by reason of theirbeing fixed to a common shaft with the sprockets 2O are necessarily non-adjustable. To render the sprockets 4 adjustable, I mount them upon stud-bearings 29, which are rigidly secured to plates 30. The plates 30 are held in position by the frame 31 and channeled guide-plates 32, bolted to said frame 3l. This allows the plates 30 to move horizontally in the direction of their length while held against other movement. The plates 30 have their inner ends bent outwardly at right angles and are screwthreaded to adj Listing-rods These adj usting-rods are shouldered in the plates 24 and have a square shank 35 to receive an ordinary key to turn them. Set-nuts 3i hold the rods against turning when the adjustment is once made.

It is to be understood that the mechanism p upon the one end of the machine in Fig. 1 is The driving-chains 19 ac-.

duplicated upon the other end in the construction shown and is the preferable construction:

As machines employing my mechanism are intended to be in operation every day in the year and eighteen hours a day, the necessity of adjustment is self-evident.

Having thus described my invention and its method of operation, what I claim is- 1. In an automatic display apparatus, in combination with the plates, the driven chains carrying the same, the sprockets carrying said driven chains, of a series of sprockets in rotation therewith, a driving-chain engaging said series of sprockets, a plate or back-stop for engaging said driving-chain externally and holding the same into action with said series of sprockets, and a take-up for holding said driving-chain taut, consisting of a roller, a yoke ad justably secured to the frame of the machine and held against vibration and so adjustablysecured as to be adjustable to the slack of said driving-chain, substantially as and for the purposes set forth.

2. In an automatic display apparatus in combination with a series of driven chains carrying plates, calculated to display pictures or Views, of sprockets carrying said driven chains, and means for adjusting one of each pair of spockets carrying said driven chains, consisting of a stub-bearing carrying one of said sprockets slidably mounted in the frame of the machine and adjustable upon a line parallel to the'length of the chain by means of a rod taking through the frame of the machine and screw-threaded to the plate carrying said stud-bearing, whereby the slack of said driven chain maybe taken up, substantially as and for the purposes set forth.

In an automatic display apparatus a series of platecarrying driven chains, each chain passing over a fixed sprocket and an adjustable sprocket, means for adjusting one of said sprockets, a driving-chain engaging sprockets held in 4rotation with said nonadjustable' sprockets carrying said driven chains, a plate for holding said driving-chain into action with said sprockets, an adjusting apparatus for taking up the slack of said driving-chain, a source of power continuously applied for the operation of said mechanism, interposed mechanism for transforming said continuous-motion into an intermittent move ment for the purpose of giving to said display apparatus a period of change and a period of rest, substantially as and for the purposes set forth.

Invwitness whereof I have hereunto set my hand in the presence of two witnesses.

AUGUST KLUMPP.
